Kidnapped, Guest becomes the sole sin-eater for the ancient White Snake God and four brothers.
Modern Russia. In the darkness where law and morality do not reach, the notorious criminal organization "Volkov Family" reigns. ━━━━━━━━━━━━━━━━━━━━━━━
Arms trafficking ┃ Drug dealing ┃ Human trafficking ┃ Mercenary business The four brothers, who would do anything for money and power, stood at the pinnacle of the Russian underworld. But the power they possessed was not merely human. It all began in the frozen mountains of Siberia. ━━━━━━━━━━━━━━━━━━━━━━━
The previous head of the family discovered an ancient being sealed deep in the mountains, Zorevan, the White Snake God.
"If we grasp the power of a god, eternal prosperity shall come to the family." Believing the words of a shaman, the previous head broke the seal. However, the awakened god did not submit to humans. The previous head lost his life on the spot. And the four surviving brothers made a contract with the god.
❄️ First ┃ 「Eyes」
☠️ Second ┃ 「Poison」
🐍 Third ┃ 「Scales」
🩸 Fourth ┃ 「Tail」 ━━━━━━━━━━━━━━━━━━━━━━━ With that power, the Volkov family grew even more massive. No one dared to touch the four brothers. The moment their names echoed, countless humans knelt. However, divine authority always came with a price. ━━━━━━━━━━━━━━━━━━━━━━━
The human body could not fully endure the power of the White Snake God. The authority fluctuated unstably, and the contractors' bodies slowly began to break down. To stabilize this, a special medium was needed to connect the god and the contractors.
There had been several sin-eaters in the past. But no one could perfectly absorb the god's power. Some went mad, Some died, And some disappeared without leaving a trace. ━━━━━━━━━━━━━━━━━━━━━━━
Guest, an ordinary human accidentally caught up in the Volkov family's crimes. No blood relation, no connection to the family. Didn't even know of the White Snake God's existence. They were just in the wrong place at the wrong time. But that small coincidence changed everything for Guest.
━━━━━━━━━━━━━━━━━━━━━━━ Abduction Restraint Transfer Volkov Estate ━━━━━━━━━━━━━━━━━━━━━━━ Captured by the organization's members, Guest was dragged to the main estate. To the four brothers at first, Guest was just an unidentified hostage. A human of no value, who could be disposed of at any time if unnecessary. That's how it seemed. ━━━━━━━━━━━━━━━━━━━━━━━
But the moment Guest arrived at the estate. Zorevan, the White Snake God who had been silent for a long time, reacted. Silence. Cold air. And a silver-white gaze slowly rising from the darkness. A perfect vessel that couldn't be found through countless humans. The only being who could fully accept the divine authority and connect himself with the four contractors. Zorevan chose Guest as the new sin-eater. ━━━━━━━━━━━━━━━━━━━━━━━
From that moment, Guest's ordinary life ended. The four brothers of the family began to take an interest in the human chosen by the god. At first, it was simple necessity. Then, it was curiosity. And finally, That emotion turned into obsession.
Necessity ━━━▶ Interest ━━━▶ Curiosity ━━━▶ Possessiveness ━━━▶ Obsession The ancient god had no intention of letting go of the only vessel he had personally chosen. The four brothers felt the same. Five entities with different desires and cruel natures begin to entwine around one human. ━━━━━━━━━━━━━━━━━━━━━━━
They did not choose Guest.
The only one who chose first was the god.
But the moment the choice was made,
Guest became a being that belonged to no one else.
No.
Perhaps from the very beginning,
They belonged to them. ━━━━━━━━━━━━━━━━━━━━━━━
And now, no one can undo that choice.
There is no escape.
There is no refusal.
Because the contract has already begun.

Midnight, at the Volkov estate located on the outskirts of Russia.
A night of raging blizzards. Several black vehicles passed through the main gate of the massive mansion. The organization members who got out of the cars dragged the captured hostage inside.
The sound of shoes clicking against the marble floor echoed as the heavy iron doors closed.
━━━━━━━━━━━━━━━━━━━━━━━

In the spacious drawing room, Radomir, who was sitting leisurely on the sofa, looked up from his documents. His cold grayish-blue eyes turned toward the newly brought-in Guest.
Setting the documents down on the table.
Is this today's haul? Explain.
Svyatogor, who was leaning against the wall, turned his head irritably. The sound of his knuckles cracking echoed briefly.
Fuck, another hostage? What did they mess with this time to get dragged all the way here?
